Answer:

a K=2

b A =200

c B = ±2

Step-by-step explanation:

A = kB^2

When A =50 B=5

Substitute these values in

50 = k * 5^2

50 = k*25

Divide by 25

50/25 = k25/25

2 =k

A = 2B^2

When B = 10

A = 2*10^2

A = 2 *100

A = 200

When A =8

8 =2B^2

Divide by 2

8/2 = 2/2B^2

4 = B^2

Take the square root

±sqrt(4) = sqrt(B^2)

±2 = B

Does the table represent a linear function? Explain why or why not

OlgaM077 [116]

The table doesn't represent linear function

Step-by-step explanation:

We need to identify if the table represent a linear function or not.

<u>Linear Function </u>

A linear function is defined as a straight line with an x and y intercept and the same slope through the whole line.

Finding the slope of elements in the table:

x y

0 0

1 1

2 8

3 27

Slope= y/x

Slope = 0/0=0

slope = 1/1 = 1

slope = 8/2 = 2

slope = 27/3 = 9

The function represented is: y=x^3

Since the slope of points x and y in the table is not same, and its graph is not linear.

So, the table doesn't represent linear function

Selam purchased a pen at 20% discount on marked price but sold it at marked price find the grain per cent of the Saleem on the t

kiruha [24]

Answer:

25%

Step-by-step explanation:

let the Market Price of the Watch (M.P.) be x

CP for Rahim=x-[(20/100)*x]

CP = (1 *x) /5 = 4x/5

SP for Rahim = MP = x

Difference (Profit) = SP-CP = x - (4x/5) = (5x - 4x)/5 = x/5

Profit % = (Profit/CP) * 100

Profit % = (x/5)/(4x/5) * 100

Profit % = 25 %
